Conversion tracking and context preserving systems and methods

ABSTRACT

When a server receives a request for an information payload from a remote device, the server may determine the device&#39;s type and identify an optionally-installable application that can be used to access the information payload on devices of that type. When the optionally-installable application is not installed on the remote device, the server may store a identifier for the remote device and send the device a redirection message via which the device can obtain and install the application. Subsequently, when the server receives an installation indication from the application executing on a remote device, the server may identify the device as having recently been redirected to install the application and store or update a record indicating that an application-installation event occurred.

FIELD

This disclosure is directed to software, and more particularly, tosystems and methods by which a server device can track and providecontext for application installations on remote client devices.

BACKGROUND

An application store (also commonly referred to as an “app” store, “app”marketplace, or the like) is a type of digital distribution platform forapplication software that users may opt to install on devices of aparticular type. In recent years, application stores have become acommon component on personal computers, smartphones, tablets, and thelike.

Application providers typically write an optionally-installableapplication for a given type of device and submit the application to anapplication-store provider, which makes the application available forusers to purchase and/or download via an application store.

Once a user has installed such an application on a given device, thedevice may be able to use the application to access information payloadsprovided by the application provider and/or by third-parties. In manycases, an application provider may also provide a website that can beused to access at least some of the same information payloads that canbe accessed by an optionally-installable application.

For example, a content provider, such as a blogging platform, socialnetwork, news portal, or the like, may provide a website by which posts,articles, or other information payloads may be accessed by web-browsersoftware executing on remote devices. That content provider may alsoprovide an optionally-installable application that can be obtained froman application store and, once installed, used to access some or all ofthe same posts, articles, or other information payloads.

In many cases, such a content provider may wish to promote itsoptionally-installable application for various reasons (e.g., a nativeapplication may provide a superior user experience than a website, thecontent provider may earn revenue when users obtain and use itsoptionally-installable application, or the like). To that end, manycontent providers detect when a visiting device is of a type for whichan optionally-installable application is available so that theirwebsites may notify the visitor that an optionally-installableapplication is available and/or encourage the visitor to obtain anoptionally-installable application.

However, such app-promotion activities can detract from the user'sexperience with a given content provider. For example, in one commonscenario, a user may encounter a link that purports to identify aninformation payload (e.g., an amusingly-captioned photograph of anadorable kitten) that the user wishes to view or otherwise consume. Uponfollowing the link to a content provider's website, the user ispresented not with an amusing and adorable kitten photograph, but with anotification indicating that the content provider has published anapplication available on the user's device.

If the user decides not to install the application, then the user mayproceed to view the desired photograph in the device's web browser,being thereby amused by the cleverness of the caption and/or theadorableness of the kitten, but being deprived of whatever benefits thenative application may provide.

On the other hand, if the user decides to obtain and install theapplication, the application typically does not “know” that the user wastrying to access a particular photograph or other resource, oftenforcing the user to search for or independently navigate to the desiredphotograph from within the application. This is but one common scenarioin which a content provider's application-promotion may hinder a user'sability to consume a desired information payload.

In an effort to address some of the shortcomings of previousapplication-promotion methods, in recent versions of the iOS operatingsystem (provided by Apple Inc. of Cupertino, Calif.), the Safari webbrowser includes a “Smart App Banner” feature. When the user visits agiven page that has an “apple-itunes-app” meta tag, a “Smart App Banner”will automatically determine whether an indicated application isavailable for and installed on the user's device. When the indicatedapplication is not installed on the user's device, tapping on the bannerwill opens the application's entry in the iOS App Store.

After the application is installed, if the user returns to the same pagein the Safari web browser, tapping the banner will open the installedapplication, and the Safari web browser will pass to the application anURL (indicated in the “apple-itunes-app” meta tag of the page) that theapplication can use to present an appropriate resource to the user.

However, if the user launches the application from the iOS App Store,from the iOS Home Screen, from the iOS Spotlight Search, or via anyother means, the application has no previously known method todetermine, for example, that the user installed the application whileattempting to access a particular web page.

DESCRIPTION

In various embodiments, as discussed below, various systems and methodsmay be employed to track and provide context for applicationinstallations on remote client devices.

The phrases “in one embodiment”, “in various embodiments”, “in someembodiments”, and the like are used repeatedly. Such phrases do notnecessarily refer to the same embodiment. The terms “comprising”,“having”, and “including” are synonymous, unless the context dictatesotherwise.

Reference is now made in detail to the description of the embodiments asillustrated in the drawings. While embodiments are described inconnection with the drawings and related descriptions, there is nointent to limit the scope to the embodiments disclosed herein. On thecontrary, the intent is to cover all alternatives, modifications andequivalents. In alternate embodiments, additional devices, orcombinations of illustrated devices, may be added to, or combined,without limiting the scope to the embodiments disclosed herein.

FIG. 1 illustrates a simplified installation-detection system in whichapplication provider 115, application store 120, client computing device125, and installation-detection server 200 are connected to network 105.

In various embodiments, network 105 may include the Internet, a localarea network (“LAN”), a wide area network (“WAN”), and/or other datanetwork.

In various embodiments, additional infrastructure (e.g., cell sites,routers, gateways, firewalls, and the like), as well as additionaldevices may be present. Further, in some embodiments, the functionsdescribed as being provided by some or all of installation-detectionserver 200, application provider 115, and/or application store 120 maybe implemented via various combinations of physical and/or logicaldevices. However, it is not necessary to show such infrastructure andimplementation details in FIG. 1 in order to describe an illustrativeembodiment.

FIG. 2 illustrates several components of an exemplaryinstallation-detection server in accordance with one embodiment. In someembodiments, installation-detection server 200 may include many morecomponents than those shown in FIG. 2. However, it is not necessary thatall of these generally conventional components be shown in order todisclose an illustrative embodiment.

In various embodiments, installation-detection server 200 may compriseone or more physical and/or logical devices that collectively providethe functionalities described herein. In some embodiments,installation-detection server 200 may comprise one or more replicatedand/or distributed physical or logical devices.

In some embodiments, installation-detection server 200 may comprise oneor more computing services provisioned from a “cloud computing”provider, for example, Amazon Elastic Compute Cloud (“Amazon EC2”),provided by Amazon.com, Inc. of Seattle, Wash.; Sun Cloud ComputeUtility, provided by Sun Microsystems, Inc. of Santa Clara, Calif.;Windows Azure, provided by Microsoft Corporation of Redmond, Wash., andthe like.

Installation-detection server 200 includes a bus 205 interconnectingseveral components including a memory 225; a network interface 210; anoptional display 215; and a central processing unit 220.

Memory 225 generally comprises a random access memory (“RAM”), a readonly memory (“ROM”), and a permanent mass storage device, such as a diskdrive. The memory 225 stores program code for a routine 400 forgenerating a unique URL (see FIG. 4, discussed below); a routine 500 forprocessing a resource request (see FIG. 5, discussed below); and aroutine 800 for processing an application-installation indication (seeFIG. 8, discussed below). In addition, the memory 225 also stores anoperating system 235

These and other software components may be loaded into memory 225 ofinstallation-detection server 200 using a drive mechanism (not shown)associated with a non-transient computer-readable medium 230, such as afloppy disc, tape, DVD/CD-ROM drive, memory card, or the like.

Memory 225 also includes database 240. In some embodiments,installation-detection server 200 may communicate with database 240 vianetwork interface 210, a storage area network (“SAN”), a high-speedserial bus, and/or via the other suitable communication technology.

In some embodiments, database 240 may comprise one or more storageservices provisioned from a “cloud storage” provider, for example,Amazon Simple Storage Service (“Amazon S3”), provided by Amazon.com,Inc. of Seattle, Wash., Google Cloud Storage, provided by Google, Inc.of Mountain View, Calif., and the like.

FIG. 3 illustrates an exemplary series of communications betweenapplication provider 115, client computing device 125,installation-detection server 200, and application store 120 inaccordance with one embodiment. The communications shown in FIG. 3 donot encompass every combination of possibilities in which the systemsand methods provided herein may be employed. Rather, the illustratedcommunications merely provide an overview of one simplified examplescenario. Additional variations and alternatives are described morefully in the Figures and description that follow.

Beginning the illustrated sequence of communications, client computingdevice 125 sends to installation-detection server 200 a request 304 fora resource identified by a unique URL that was previously generated byinstallation-detection server 200 according to a routine such as routine400, shown in FIG. 4. In many cases, the request 304 may be sent by aweb-browser application executing on client computing device 125.

In many embodiment, request 304 may conform to the Hypertext TransferProtocol (“HTTP”) application protocol, according to which request 304may include metadata values associated with several HTTP header fields.

Installation-detection server 200 determines 309 a device type of therequesting device and identifies the requesting device. In theillustrated scenario, installation-detection server 200 identifies therequesting device via a “fingerprint” identifier, based at least in parton metadata associated with the resource-request, that is likely todistinguish the requesting device from most or all other devices.

As discussed above, the request may conform to the HTTP protocol, whichdefines many standard HTTP header fields, and many other non-standardrequest headers are commonly employed. In various embodiments, some orall of the HTTP header field values provided when the client computingdevice 125 makes a request may be processed along with additionalrequest metadata to create a “fingerprint” of the request. Such“fingerprint” identifiers are discussed further in relation to block 630of FIG. 6, below.

Installation-detection server 200 processes the request, includingidentifying 313 a destination URL associated with the unique URL, andidentifying an installable application associated with thepreviously-generated unique URL and the destination device type.

Installation-detection server 200 determines 317 that the installableapplication is not installed on the requesting device. For example, inone embodiment, installation-detection server 200 may provide to clientcomputing device 125 a piece of executable code (e.g., a JavaScriptfunction) for execution on client computing device 125 that may reportto installation-detection server 200 whether the device can handle a URLor URI scheme that is associated with the installable application inquestion.

The generic syntax for URI schemes is defined in Request for Comments(“RFC”) memorandum 3986 published by the Internet Engineering Task Force(“IETF”). According to RFC 3986, a URI (including a URL) consists offour parts:<scheme name>: <hierarchical part>[?<query>][#<fragment>]

A URI begins with a scheme name that refers to a specification forassigning identifiers within that scheme. The scheme name consists of aletter followed by any combination of letters, digits, and the plus(“+”), period (“.”), or hyphen (“-”) characters; and is terminated by acolon (“:”).

The hierarchical portion of the URL is intended to hold identificationinformation that is hierarchical in nature. Often this part isdelineated with a double forward slash (“//”), followed by an optionalauthority part and an optional path.

The optional query portion is delineated with a question mark andcontains additional identification information that is not necessarilyhierarchical in nature. Together, the path part and the query portionidentify a resource within the scope of the URI's scheme and authority.The query string syntax is not generically defined, but is commonlyorganized as a sequence of zero or more <key>=<value> pairs separated bya semicolon or ampersand, for example:key1=value1;key2=value2;key3=value3 (Semicolon), orkey1=valuel&key2=value2&key3=value3 (Ampersand)

Much of the above information is taken from RFC 3986, which providesadditional information related to the syntax and structure of URIs. RFC3986 is hereby incorporated by reference, for all purposes.

Installation-detection server 200 records 322 contextual metadataassociated with the request, including information such as some or allof the following: the identified destination URL, a date and/or time atwhich the request was received, the requesting-device “fingerprint”, anapplication-identifier associated with the installable application, andthe like.

Installation-detection server 200 assembles 326 a redirection messagethat will allow the requesting device to obtain the installableapplication. There are many well-known methods of providing aredirection message, including using HTTP redirection status codes(e.g., 301, 302, 307, and the like), using a “Refresh” meta tag or HTTPrefresh header, using a JavaScript redirect, and the like.

A typical redirection message that will allow the requesting device toobtain the installable application may include an application-identifierthat identifies the installable application in question to applicationstore 120.

In some embodiments, the redirection message may include a compound URLsuch as described in U.S. Pat. No. 8,433,800 (incorporated herein). Seealso subroutine 700, shown in FIG. 7 (discussed below).

Installation-detection server 200 sends to client computing device 125the redirection message 330.

Acting upon the redirection message, client computing device 125 sendsto application store 120 a request 334 for the installable application.

Application store 120 processes 339 the request and sends to clientcomputing device 125 the installable application 343.

Client computing device 125 installs and opens 347 the installableapplication.

When the installable application is run after being installed, it isconfigured to cause client computing device 125 to send toinstallation-detection server 200 an installation indication 352indicating that the installable application was installed on clientcomputing device 125. In the illustrated scenario, the installationindication further requests a “context” to present to the user, such asa resource that the user has recently evidenced a desire to consume.

Installation-detection server 200 determines 356 a device type of therequesting device and identifies the requesting device. In theillustrated scenario, installation-detection server 200 identifies therequesting device via a “fingerprint” identifier, based at least in parton metadata associated with the resource-request, that is likely todistinguish the requesting device from most or all other devices.

As discussed above, the request may conform to the HTTP protocol, whichdefines many standard HTTP header fields, and many other non-standardrequest headers are commonly employed. In various embodiments, some orall of the HTTP header field values provided when the client computingdevice 125 makes a request may be processed along with additionalrequest metadata to create a “fingerprint” of the request. Such“fingerprint” identifiers are discussed further in relation to block 630of FIG. 6, below.

Installation-detection server 200 matches the just-determinedfingerprint with the recently-recorded fingerprint discussed above.

Having received an installation indication from a device that can bematched to a recent unique URL request and that was recently redirectedto application store 120, installation-detection server 200 infers thatthe installable application was installed in response to the redirectionand records 365 (e.g., in database 240) an application-installationevent associated with client computing device 125 and/or thepreviously-generated unique URL.

Installation-detection server 200 obtains 369 the recently-recordeddestination URL that is associated with the recent unique URL requestsent by client computing device 125.

Installation-detection server 200 assembles 373 a redirection messagethat will allow the installable application executing on clientcomputing device 125 to obtain the resource identified by thedestination URL.

Installation-detection server 200 sends to client computing device 125the redirection message 377.

Client computing device 125 sends to application provider 115 a request382 for the resource identified by the destination URL.

Application provider 115 processes 386 the request and sends to clientcomputing device 125 the requested resource 390.

The installable application executing on client computing device 125presents 395 the resource that is associated with the unique URL thatclient computing device 125 requested (e.g. via a web-browserapplication) before the installable application was installed on clientcomputing device 125.

Installation-detection server 200 sends to application provider 115 areport 399 indicating that client computing device 125 (or a device ofclient computing device's 125 type) installed the installableapplication after requesting the unique URL.

FIG. 4 illustrates a routine 400 for generating a previously-generatedunique URL, such as may be performed by an installation-detection server200 in accordance with one embodiment.

In block 405, routine 400 obtains an identifier (e.g. a URL) identifyingan information payload, such as a web page, media content, or the like.In some cases, the identifier may be obtained from a content provider,and the information payload may be an asset provided by that contentpartner.

In block 410, routine 400 determines one or more device types to whichthe information payload may be delivered. In some cases, a differentpayload or a differently-formatted payload may be delivered to differentdevice types. Additional disclosure about generating a unique URL thatcan be used to access device-type-specific information payloads may befound in U.S. Pat. No. 8,438,245 (incorporated herein).

Beginning in opening loop block 415, routine 400 processes each devicetype (as determined in block 410) in turn.

In decision block 425, routine 400 determines whether anoptionally-installable application can be used to access the informationpayload on the current device type. Typically, the content provider orother entity that provided the information payload (as obtained in block405) may provide an identifier identifying an optionally-installableapplication that can be used to access the information payload on thecurrent device type. If such an identifier was provided, routine 400proceeds to block 430. Otherwise, routine 400 proceeds to ending loopblock 435.

In block 430, routine 400 associates the optionally-installableapplication determined in decision block 425 with the informationpayload (as obtained in block 405), e.g., by storing or updating arecord in database 240.

In ending loop block 435, routine 400 iterates back to opening loopblock 415 to process the next device type (as determined in block 410),if any.

In block 440, routine 400 stores, e.g. in database 240, the informationpayload and/or an identifier identifying the information payload.

In block 445, routine 400 generates a unique URL associated with theinformation payload stored in block 440.

In block 450, routine 400 stores the unique URL (as generated in block445) and provides it for exposure to remote computing devices. Asdiscussed further in U.S. Pat. No. 8,438,245 (incorporated herein), invarious embodiments, the previously-generated unique URL may be exposedto remote computing devices in a number of forms, including as a 2-dbarcode or other machine-scannable code; as a link published via a website or otherwise included in an HTML or similar document; or the like.

Routine 400 ends in ending block 499.

FIG. 5 illustrates a routine 500 for processing a resource request, suchas may be performed by an installation-detection server 200 inaccordance with one embodiment.

In block 505, routine 500 receives, from a remote computing device, arequest for a unique URL that was previously generated according to amethod such as that shown in FIG. 4, discussed above. In someembodiments, the request may conform to the HTTP protocol.

In block 510, routine 500 identifies a device type of the remotecomputing device. For example, in one embodiment, metadata associatedwith an HTTP request, such as a “User-Agent” header or the like, may beused to determine a device type of the remote computing device.

In subroutine block 600, routine 500 calls subroutine 600 (see FIG. 6,discussed below) to determine an identifier that can be used todistinguish the requesting remote computing device from some or allother remote computing devices that may interact with routine 500.

In block 515, routine 500 identifies an information payload associatedwith unique URL. For example, in one embodiment, routine 500 may locatea record in database 240 that was previously keyed to or otherwiseassociated with the previously-generated unique URL, such as describedin connection with block 430 of FIG. 4 (above).

In block 520, routine 500 identifies an optionally-installableapplication that can be used to access the information payload on therequesting device. For example, in one embodiment, routine 500 maylocate a record in database 240 that was previously keyed to orotherwise associated with the unique URL, such as described inconnection with block 430 of FIG. 4 (above).

In decision block 525, routine 500 determines whether theoptionally-installable application (as identified in block 520) isinstalled on the requesting remote computing device. For example, in oneembodiment, routine 500 may provide to the remote computing device apiece of executable code (e.g., a JavaScript function) for execution onthe remote computing device that may report to routine 500 whether thedevice can handle a URL or URI scheme that is associated with theoptionally-installable application (as identified in block 520).

If the optionally-installable application is determined to be installed,routine 500 proceeds to block 530. Otherwise, routine 500 proceeds toblock 535.

In block 530, routine 500 obtains an identifier by which the remotecomputing device may launch the optionally-installable application (thatwas determined in decision block 525 to be installed) to access theinformation payload.

In block 535, routine 500 obtains an identifier by which the remotecomputing device may obtain and install the optionally-installableapplication that was determined to be not installed on the requestingremote computing device.

In either case, routine 500 may obtain an appropriate identifier bylocating a record in database 240 that was previously keyed to orotherwise associated with the unique URL, such as described inconnection with block 430 of FIG. 4 (above).

In subroutine block 700, routine 500 calls subroutine 700 (see FIG. 7,discussed below) to generate a redirection message by which the remotecomputing device can launch and/or install the optionally-installableapplication according to the application identifier obtained in block530 or block 535.

In block 540, routine 500 provides to the remote computing device theredirection message as generated in subroutine block 700.

In block 545, routine 500 stores and/or updates a record (e.g., indatabase 240) indicating that at the current date and/or time, theremote computing device (as identified in subroutine block 600)requested the information payload (as identified in block 515) and wasredirected according to the redirection message (as generated insubroutine block 700).

Routine 500 ends in ending block 599.

FIG. 6 illustrates a subroutine 600 for identifying a given remotecomputing device based on a given request, such as may be performed byan installation-detection server 200 in accordance with one embodiment.

In various embodiments, various methods may be available to identify agiven remote computing device to at least some degree of certainty.Three common methods are described below in an alternative decisiontree. However, in many cases, a given embodiment may be configured touse a particular method, without evaluating whether the otheralternatives are available.

In some embodiments, a given remote computing device may be configuredto provide a unique serial number or other device identifier tosubroutine 600 upon request. In decision block 605, subroutine 600determines whether the remote computing device will provide such aunique identifier. If so, subroutine 600 proceeds to block 610.

In block 610, subroutine 600 requests and obtains a unique serial numberor other device identifier from the given remote computing device. Inmany embodiments, such a unique serial number or other device identifiermay definitively distinguish the given remote computing device from allother devices.

In some embodiments, subroutine 600 may be configured to integrate witha third-party entity, such as a mobile network operator, wirelessservice provider, wireless carrier, or the like, that is able toidentify the given remote computing device using an identifier such asan International mobile Subscriber Identity (“IMSI”), InternationalMobile Station Equipment Identity (“IMEI”), MSISDN, or the like. Indecision block 615, subroutine 600 determines whether such a third-partywill identify the given remote computing device. Or alternately, in someembodiments, subroutine 600 may be executing on a device operated bysuch an entity. If so, then subroutine 600 proceeds to block 620.

In block 620, subroutine 600 obtains the third-party-provided uniqueidentifier. In many embodiments, such an identifier may definitivelydistinguish the given remote computing device from all other devices.

Otherwise, if no definitive identifier is obtainable, in block 625,subroutine 600 obtains metadata associated with the given remotecomputing device and/or the given request.

In many embodiments, the given request may conform to the HTTP protocol,which defines many standard HTTP header fields. Additionally, manynon-standard request headers are commonly employed. In such embodiments,subroutine 600 may obtain metadata values provided via HTTP headerfields, as well as additional metadata such as a current date and/ortime.

In block 630, subroutine 600 determines a (non-necessarily-unique)device “fingerprint” identifier based on metadata (as obtained in block625). In various embodiments, some or all of the HTTP header fieldvalues provided when the given remote computing device makes the givenrequest may be processed, possibly along with additional requestmetadata (e.g., a current date and/or time) to create a “fingerprint” ofthe request.

For example, in one embodiment, an IP address associated with the clientcomputing device 125 may be combined with the value of a “User-Agent”HTTP request header to create a request fingerprint that, while it maynot uniquely identify the client computing device 125, may distinguishrequests made by the client computing device 125 from requests made bymost other devices.

To combine metadata into a request “fingerprint”, subroutine 600 mayemploy techniques such as concatenating the metadata values and/orprocessing the metadata values via a cryptographic hash function.

Subroutine 600 ends in ending block 699, returning to the caller theidentifier obtained or determined in block 610, block 620, or block 630.

FIG. 7 illustrates a subroutine 700 for generating a compound URL for agiven information payload and a given optionally-installableapplication, such as may be performed by an installation-detectionserver 200 in accordance with one embodiment.

FIG. 7 illustrates a simplified version of compound-URL systems andmethods similar to those described in U.S. Pat. No. 8,433,800(incorporated herein). In some embodiments, subroutine 700 may utilizeadditional features variously described in U.S. Pat. No. 8,433,800.

In block 705, subroutine 700 determines a resource URL associated withthe given information payload. In some embodiments, the resource URL maybe suitable for accessing the information payload via a general-purposeweb-browsing application. In other embodiments, the resource URL may besuitable for accessing the information payload via the givenoptionally-installable application on one or more computing platforms.

In block 710, subroutine 700 determines an application URL associatedwith a given optionally-installable application that can be used toaccess the information payload. In some cases, the application URL mayinclude a URL scheme that is associated with the givenoptionally-installable application on one or more types of computingdevices, such that resolving the application URL on such a device willinvoke the optionally-installable application to access the informationpayload.

In other cases, the application URL may identify the givenoptionally-installable application within an application store on aparticular computing platform, such that resolving the application URLon a certain type of device will invoke an application store applicationto obtain and install the optionally-installable application.

In block 715, subroutine 700 designates either the application URL orthe resource URL as a “host” URL, and the other as a “alternative” URL.Generally, providing a compound URL may allow a remote device to accessthe information payload via an optionally-installable application if theoptionally-installable application is installed or to obtain theoptionally-installable application if it is not installed.

In some embodiments, when processing a compound URL, a computing devicemay be configured to attempt to resolve the “alternative” URL first,falling back to the “host” URL if the “alternative” URL cannot beresolved (e.g. because an optionally-installable application is notinstalled). In other embodiments, a computing device may be configuredto attempt to resolve the “host” URL first, falling back the“alternative” URL if the “host” URL cannot be resolved.

In some embodiments, subroutine 700 may designate the “host” URL and the“alternative” URL such that a computing device of a certain type willfirst attempt to resolve the resource URL to invoke theoptionally-installable application to access the information payload,falling back to the application URL to obtain and install theoptionally-installable application if invoking theoptionally-installable application fails.

In block 720, subroutine 700 obtains a predetermined alternative-URLkey. As discussed further in U.S. Pat. No. 8,433,800 (incorporatedherein), in various embodiments, subroutine 700 may obtain a key such as“appURI” or “altURI” to indicate the presence of a “alternative” URLwithin a compound URL.

In block 725, subroutine 700 inserts a “alternative” URL key/value pairinto the “host” URL to form a compound URL. In various embodiments,inserting the “alternative” URL key/value pair may includepercent-encoding the “alternative” URL, or otherwise encoding the“alternative” URL such that it can be validly represented within thequery portion of the “host” URL according to the scheme named in the“host” URL.

Subroutine 700 ends in ending block 799, returning the compound URLformed in block 725 to the caller.

FIG. 8 illustrates a routine 800 for processing anapplication-installation indication, such as may be performed by aninstallation-detection server 200 in accordance with one embodiment.

In various embodiments, an optionally-installable application may beconfigured to contact installation-detection server 200 when theoptionally-installable application is launched after being installed ona remote computing device. In block 805, routine 800 receives such aninstallation indication from an optionally-installable applicationinstalled and executing on a remote computing device. In variousembodiments, receiving the installation indication may include receivinga request for a first-run resource identified by a predetermined URL,receiving a message and/or data via a web application programminginterface, or the like.

In subroutine block 600, routine 800 calls subroutine 600 (see FIG. 6,discussed above) to determine an identifier that can be used todistinguish the installation-indicating remote computing device fromsome or all other remote computing devices that may interact withroutine 800.

In decision block 820, routine 800 determines whether the remotecomputing device (as identified in subroutine block 600) recentlyrequested an information payload via a unique URL, as described inconnection with block 505 (see FIG. 5, discussed above).

For example, in one embodiment, routine 800 may locate a record indatabase 240 that was previously keyed to or otherwise associated withthe remote computing device (as identified in subroutine block 600),such as described in connection with block 545 (see FIG. 5, discussedabove).

If in decision block 820, routine 800 determines that the remotecomputing device (as identified in subroutine block 600) recentlyrequested such an information payload, then routine 800 proceeds todecision block 825. Otherwise, routine 800 proceeds to ending block 899.

In decision block 825, routine 800 determines whether, upon requestingthe information payload, the remote computing device (as identified insubroutine block 600) was redirected with a message enabling the remotecomputing device to obtain and install the optionally-installableapplication, as described in connection with block 540 (see FIG. 5,discussed above).

For example, in one embodiment, routine 800 may locate a record indatabase 240 that was previously keyed to or otherwise associated withthe remote computing device (as identified in subroutine block 600),such as described in connection with block 545 (see FIG. 5, discussedabove).

If in decision block 825, routine 800 determines that it has received aninstallation indication from a device that can be matched to a recentunique URL request and that was recently redirected to application store120, routine 800 may infer that the optionally-installable applicationwas installed in response to the redirection, in which case, routine 800proceeds to block 830. Otherwise, routine 800 proceeds to block 835.

In block 830, routine 800 records (e.g., in database 240) anapplication-installation event associated with some or all of the remotecomputing device (as identified in subroutine block 600), its devicetype, the information payload, and/or the unique URL.

In block 835, routine 800 provides the previously-requested informationpayload for presentation on the remote computing device via theinstalled and executing optionally-installable application.

Routine 800 ends in ending block 899.
